Looks like another point for the “Legalize It” movement…
Smoking a joint once a week or a bit more apparently doesn’t harm the lungs, suggests a 20-year study that bolsters evidence that marijuana doesn’t do the kind of damage tobacco does.
The study by researchers at the University of California, San Francisco, and the University of Alabama at Birmingham was released Tuesday by the Journal of the American Medical Association. Unlike cigarette smokers, marijuana users tend to breathe in deeply when they inhale a joint, which some researchers think might strengthen lung tissue. But the common lung function tests used in the study require the same kind of deep breathing that marijuana smokers are used to, so their good test results might partly reflect lots of practice, said Kertesz, a drug abuse researcher and preventive medicine specialist at the Alabama university.
On average, cigarette users smoked about 9 cigarettes daily, while average marijuana use was only a joint or two a few times a month – typical for U.S. marijuana users, Kertesz said.
The analyses showed pot didn’t appear to harm lung function, but cigarettes did. Cigarette smokers’ test scores worsened steadily during the study. Smoking marijuana as often as one joint daily for seven years, or one joint weekly for 20 years was not linked with worse scores. Very few study participants smoked more often than that.
Cigarettes are bad and marijuana…. not so much? Why does this seem like common sense to us? What do you think? Is this a step towards legalizing the herb or just comparing 2 of the same evils?
